Description quiet.dragon 2010-03-12 19:28:24 UTC 
Description of problem:

I have a RAID1 system comprising two identical disks. I remove one of the pair leaving the other.

I can boot the remaining degraded RAID1 system successfully.

For each of the degraded RAID1 partitions I execute:

mdadm --grow --force -n 1 /dev/md0
  etc

This creates a set of singleton RAID1 partitions -- no longer degraded, but containing only a single disk.

I can no longer boot the system.

dracut tries to reassemble the RAID1 set, and fails to assemble the root partition.


Version-Release number of selected component (if applicable):

Fedora 12


How reproducible:

Consistently reproducible.

Steps to Reproduce:
1. As described above
2.
3.
  
Actual results:

Failure to boot.

Should boot.
